Depth sensing imaging pixels include pairs of left and right pixels forming an asymmetrical angular response to incident light. A single microlens is positioned above each pair of left and right pixels. Each microlens spans across each of the pairs of pixels in a horizontal direction. Each microlens has a length that is substantially twice the length of either the left or right pixel in the horizontal direction; and each microlens has a width that is substantially the same as a width of either the left or right pixel in a vertical direction. The horizontal and vertical directions are horizontal and vertical directions of a planar image array. A light pipe in each pixel is used to improve light concentration and reduce cross talk.

A system for video based registration between images during a skeletal medical procedure includes a stereoscopic camera, a two dimensional image detector and a registration processor. The camera is associated with a stereoscopic coordinate system, the camera acquires a stereoscopic image pair of fiducial marks fixed onto a skeletal structure. Fiducial representations of the fiducial marks appear on the stereoscopic image pair, and a skeletal representation of the skeletal structure appears on two different 2D images. The registration processor registers a stereoscopic coordinate system with a 3D coordinate system associated with a volumetric image detector, and superimposes 3D information on at least one volumetric image. The registration processor registers the stereoscopic coordinate system with the 3D coordinate system by registering the stereoscopic coordinate system with the 2D coordinate system and by registering the 2D coordinate system with the 3D coordinate system.

A stereoscopic endoscope employing a single light sensor array and a lenticular lens layer located at a proximal end of the endoscope, a pair of periscopic prisms located at a distal end of the endoscope and an optical relay assembly array located between the pair of periscopic prisms and the light sensor array. One prism of the pair of periscopic prisms receives a right view of an object and another prism of the pair receives a left view of the object. The interpupilar distance (IPD) between the right and left view is substantially large, thereby increasing the resolution of a stereoscopic image which is eventually displayed on a display. Another embodiment includes a set of three light sensor arrays, a light director and three lenticular lens layers. Each light sensor array detects light at a predetermined range of wavelengths (e.g. red, green and blue).
